Very nice, thanks for posting. I actually play my 8 th patrol, Narvik, searching for a contact.
The map work is interesting. The setting up of the attack too. U like visual and periscope always up, dont use much the hydro, and stimes lucky not to be seen. Also, u might want to have a speed of 1-2 knots to maintain depth for Torps launch, its more realistic.
I still miss the external view - its nice to watch the torpedoes, and I try not to use it when detcted by destroyers. keep them coming.
